OIL-BURNER.

SPECIFICATION forming' part of Letters Patent No. '723.206, dated March17, 1903.

Application iiled October 9, 1902. Serial No. 126,526. (No model.)

To all whom t ina/y concern.-

Be it known that I, HARRY LUCKENBACH,

a citizen of the United States, residing at Seattle, in the county ofKing and State of Wash- 5 iugton, have invented certain new anduseful yImprovements in Oil-Burners, of which the following is a specification;reference being had therein to the accompanying drawings.

This invention relates to oil-burners, and Io specifically to animprovement inthe oilburner shown and described in my Letters Patent No.639,257, dated December 19, 1899; and the object of the invention-is toproduce an oil-burner capable of thoroughly Vaporizing the heaviergrades of hydrocarbon oils and generally to renderthc device moresimple,'convenient, and of higher efiiciencyin operation. Y

Inl the accompanying drawings, Figure 1 is bodying my invention. Fig. 2is a horizontal section on line 2 2 of Fig. 1. Fig, 3 is a `transverse,section taken on lines 3 Stof Figs.

1 and 2. y The improved burner comprises a casing d, `preferablyrectangularin cross-section,which is divided by partitions b intocompartments cand d. The compartments c are open at both ends, theirforward ends being connect- 3o ed and terminate in a attened orifice c',eX- tending the entire width of the compartments. The inuercompartmentd, forming an oil-chamber, is closed at the back end and terminates in aflattened outlet CZ', positioned in the same plane as the tiret-namedorifice c and at a short distance to the rear thereof.

` A steam-supplypipe e projectsintothe said oil-chamber and terminates ashortdistance back of the outlet d' in a iiattened nozzle e.

4o Extending transversely across the said oilchamber is a metal sheet orpan f, sloping slightly toward the forward end and formed of a convex orhipped central portion f', with lateral wings f", Fig. 3, which aresupported on shelf-pieces g of the casing. The said wings are in atransverse direction horizontal,

or nearly so, and provided with a plurality of perforations '11,preferably formed by punching the sheet from the `under side, so as toAn oil-supply pipe h extends through the v.outer casing and the upper ofsaid, partitions into the said Oilehambe-r adjacent toits back end.

The operation of -the burner is as follows: Steam being first admittedthrough the pipe e raises Vthe tem perature-of the oil-chamber (l, andparticularly of the pan f, so that when fuel-oil is delivered upon thelatter itis rapidly vaporized and expelled with the steamjet, to beintimately mixed with the converging streams of air drawn in through theducts c and consumed within a tile 7c or other com'- bustion-chamber. Inthe event of the oil being delivered upon the said pan in suchquantities as to retard its immediate vaporization, then after spreadingover the upper surface of the wings the surplus would b e spilled orsprinkled through the said pan-perforations, to be vaporizedtherebeneath.

,When working under extremelyA cold atmospheric conditions, theair-ducts may ad- NantageOUsl'y receive their supply of' combustive airfrom a heater, or the outer aircontact surfaces of saidburner-partitions may be protected from being chilled by a covering ofan efiicient heat non-conductor; but ordinarily I und in practice thatradiated heat from the steam-supply pipe is suiicient t0 vaporize theheaviest of oils which have come to my notice.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

1. In a device of the class described, the combination of an oil-chamberhaving a contracted opening at its delivery end, a metal sheet or panpositioned interiorly of said oilchamber, asteam-supply pipe projectingwithin said oil-chamber and terminating in a flattened nozzle at ashortdistance to the rear of the said opening of the oil-chamber, air-ductslocated above and below thecsaid oil-chamber and having a commondischargeopening in advance of and in line with the aforesaiddischarge-openings of the steam-pipe and oilchamber, and an Aoil-supplypipe extending Vinto said oil-chamber, substantially as and for thepurposes set forth.
